What does it mean when the eyebrows of middle-aged and elderly men grow longer? Does it mean longevity? know the reason
53-year-old Yang Bo found that his eyebrows were so long that they almost covered his eyes, so he wanted to go to a barber shop to have his eyebrows trimmed. Unexpectedly, Brother Wang at the barber shop saw Uncle Yang's long eyebrows, and instead smiled and said that it was a good thing and that they should not be cut.
Brother Wang said that since ancient times, long-lived old people have always had white eyebrows, which shows that longer eyebrows are a feature of longevity, and no one else can ask for it.
Hearing this, Uncle Yang suddenly realized that he had a long-lived physique. It seems that after getting old, the longer the eyebrows, the better, and he left with a smile. But are eyebrows really related to longevity? Why do many people gradually grow longer eyebrows after they reach middle age?
1. What is the function of the presence of eyebrows?
The facial features of a person include eyebrows, eyes, nose, mouth and ears. Among them, the eyes can see the world, the nose can smell, the mouth can eat, and the ears can hear sounds. As the first of the five senses, what is the function of the eyebrows?
In fact, eyebrows have a great effect on the human body.
Function 1. Block sweat
The most important function of eyebrows is to block sweat. Sweating is a normal physiological phenomenon of human beings. Factors such as hot weather, exercise, and eating spicy food can cause sweating. When sweat flows down, the eyebrows located above the eyes block the sweat and divert the sweat to the nose and cheeks, thereby protecting the eyes from irritation and damage. In addition to sweat protection, eyebrows are also resistant to dandruff and sand.
Function 2. Expressing expressions
The various shapes of eyebrows, such as raised, drooped, stretched, compact, etc., can reflect a person's emotions in real time, and are the key to many micro-expressions.
It can be said that besides the eyes, the eyebrows are the organs that can best reveal a person's true thoughts. When FBI personnel in the United States come into contact with people, they always stare at the changes in the eyes and eyebrows of the other person, thus observing the other person's inner world.
Function 3. Affect the appearance
The impact of eyebrows on a person's appearance can be described as cosmetic surgery. If the eyebrows look good, the overall facial features will look more refined. This is why, from ancient times to the present, women in different cultural backgrounds have outlined and drawn their eyebrows during makeup.
2. What does it mean when the eyebrows of middle-aged and elderly men grow longer?
First of all, the length of eyebrows can really tell the length of life?
In Chinese physiognomy, eyebrows represent the longevity palace, and it is believed that the length of a person's lifespan can be judged from the shape of his eyebrows. The representative book of Physiognomy of Jianghu School in the Song Dynasty, "Shen Xiang Quan Bian", mentioned that "the eyebrows are long and the longevity is undoubtedly long".
Chinese medicine also believes that whether the eyebrows are thick or not is related to the strength of a person's blood and kidney qi. If a person's eyebrows are sparse, short and easy to fall off, it reflects that his blood is weak. If a person's eyebrows are thick, thick and moist, it reflects that he is vigorous and strong.
However, there is actually no scientific evidence for a cause-and-effect relationship between longevity and eyebrow growth . The length of a person's eyebrows is mainly related to two factors: age and hormones.
·age
The growth cycle of eyebrows is relatively short, and it will be renewed every 3-4 months. Due to the fast metabolism of young people, the eyebrows will continue to be renewed, so they can't grow too long. Each eyebrow can grow to a length of 0.4-1 cm at most.
As the metabolism slows down in the elderly , the eyebrows will gradually stop renewing, so they will become longer. In other words, the lengthening of eyebrows is actually a manifestation of the decline in the function of the body's functional regulation mechanism.
·hormone
In addition, eyebrows are also affected by hormones in the body. Especially for men, if the androgen level in the body is too high and the testosterone index is high, the hair growth rate will become faster. And with age, the hair follicles will become more sensitive, so it is more difficult to resist the stimulation of testosterone, so that the growth period of the hair becomes longer, so the eyebrows grow more vigorously.
Although the length of eyebrows cannot tell the length of a person's lifespan, eyebrows may imply a person's physical condition.
1. Eyebrows turn white
Graying of the eyebrows may be a precursor to Vitiligo . Vitiligo is a disease caused by depigmentation. When Vitiligo develops to a certain extent, it will cause the hair to turn white, including the eyebrows.
After suffering from vitiligo on the head and face, the patient's eyebrows will appear white spots, which is due to the loss of melanin, which leads to the gradual graying of the hair.
2. Partial shedding of outer eyebrows
If there is partial loss of the outer side of the eyebrows, it may be hypothyroidism or hypophyseal hypofunction of the pituitary gland.
Hypophysis of the pituitary gland can cause hypothyroidism. When the thyroid is hypofunctioning, the metabolic capacity of the whole body will decrease, and hair such as eyebrows may fall off due to malnutrition.
3. Eyebrows suddenly fall off overnight
Sudden loss of some or all of the eyebrows may be caused by alopecia areata . Alopecia areata is a sudden onset of localized patchy hair loss associated with poor sleep, stress and immune abnormalities. When alopecia areata is not controlled in time, it may affect other hairs, such as eyebrows and eyelashes.
4. The eyebrows of young people suddenly grow longer
Peng Yuqing, director of the Prevention and Treatment Center and the Sub-Health Department of Dongfang Hospital of Beijing University of Chinese Medicine, said that if the eyebrows of young people suddenly grow longer, it is likely that the regulation mechanism of body functions is hindered . Usually, you don’t have to worry too much about this situation. You need to adjust your diet and living habits, ensure regular work and rest, reduce going to bed late and staying up late, exercise more, and recover slowly.
3. Don't pull out your eyebrows casually, think clearly before you write your eyebrows
In recent years, more and more people pay attention to the beauty of eyebrows. When modifying the shape of eyebrows, many people like to use tweezers to pluck their eyebrows directly. However , the harm of pulling eyebrows is not small , and it may affect your health.
There are abundant blood vessels and nerves around the eyebrows. Pulling eyebrows is a bad stimulus to these blood vessels and nerves, which may often cause bleeding, pain and infection. In severe cases, it can also cause diseases such as folliculitis, blurred vision and ptosis. So, don't pluck your eyebrows casually at ordinary times.
In addition to plucking eyebrows, many people also tattoo their eyebrows. However, eyebrow tattooing itself is a kind of minimally traumatic skin coloring . The eyebrow tattooer may cause infection, allergy or foreign body growth due to improper operation by the tattoo artist, allergies to dyes and anesthetics or some of their ingredients, autoimmune problems, etc. Granuloma.
In addition, there are risks in eyebrow washing and color supplementation. Therefore, if you have the idea of tattooing eyebrows, it is recommended to go to a professional and formal place, and pay attention to whether there is any abnormality.
Changes in eyebrows can reflect the health of the body, but long eyebrows do not necessarily mean longevity . Eyebrows can protect the eyes, express emotions and affect the value of the face, so they cannot be pulled out randomly .
